Zhou Huai knelt in the back alley of the funeral home for three hours. Rain dripped down the metal prosthesis on his left arm, and he clutched a yellowed photo of a witness in his palm. Chen Yan held an umbrella and stopped in front of him without saying anything or holding it. The photo of the "accident" scene three years ago was exactly this one - the witness had a pinhole in his neck, and Chen Yan's report said "suicide by overdose." Zhou Huai's first sentence was: "Do you remember that he has a birthmark behind his left ear?" Chen Yan's pupils shrank suddenly. He turned to leave, but Zhou Huai stuffed the photo into the inner pocket of his windbreaker: "He's not dead, you buried a substitute." Hook: After Chen Yan returned home, he discovered that on the back of the photo, there was a series of numbers written in blood - the exact number of the physical evidence he destroyed three years ago.
